Abstract

Disclosed herein is a supercooling apparatus of a simultaneous cooling and heating type multiple air conditioner. The supercooling apparatus comprises a liquid pipe header connected to an outdoor heat exchanger, a plurality of branch liquid pipes branched from the liquid pipe header and connected to a plurality of indoor heat exchangers, respectively, and a supercooling mechanism mounted at at least one of the branch liquid pipes for cooling refrigerant flowing to the indoor heat exchangers. The liquid refrigerant discharged from the heating-side indoor heat exchangers is supercooled by supercooling heat exchangers, and is then introduced into the cooling-side indoor heat exchangers. Consequently, noise generated from the cooling-side heat exchangers during the simultaneous cooling and heating operation is reduced, and cooling capacity of the multi air conditioner is improved.

Description

technical field [0001] The present invention relates to a simultaneous cooling and heating type compound air conditioner, in particular to a simultaneous cooling and heating type compound air conditioner supercooling device, which can reduce the heat exchange rate from the cooling side during the simultaneous cooling and heating process. reduce the noise generated by the air conditioner and improve the cooling capacity of the duplex air conditioner. Background technique [0002] Generally speaking, the simultaneous cooling and heating air conditioner is a kind of duplex air conditioner. The simultaneous cooling and heating type air conditioner simultaneously performs cooling and heating operations to individually cool or heat a room in which the indoor unit of the air conditioner is installed. [0003] Specifically, this simultaneous cooling and heating type air conditioner is constructed as follows: when one or more rooms are to be heated, the indoor units installed in the...
